Claims

[Scope of utility model registration request]

The slop tank is shelled, and a first pump is provided that sucks oil in the oil tank through a first suction pipe and transports it to a predetermined location through a first discharge pipe, and the oil in the slop tank is sucked into a second suction pipe. A second pump is provided for suctioning the slop through the pipe and transporting it to a predetermined location via the second discharge pipe, one end of which communicates with both the first and second discharge pipes, and the other end of which is connected to the slop tank. A stripping pipe is provided with an eductor interposed in the circulation pipe, one end of which communicates with the eductor, and the other end of which opens at the bottom of the oil tank, one end of which is located upstream of the ejector of the circulation pipe. A cleaning pipe is provided, the other end of which is connected to a cleaning tool disposed in the upper part of the oil tank, and the first and second discharge pipes are connected to a downstream part of the circulation pipe communication part of the first and second discharge pipes and to the second suction pipe. , second and third flow rate regulating valves are respectively provided, a pressure gauge is provided at a location upstream of the cleaning communication location of the circulation pipe, and first and second flow meters are provided at a location downstream of the ejector of the second suction pipe and circulation pipe. At the same time, a liquid level gauge is installed in the slop tank, and signals from the pressure gauge and the first and second flow meters are inputted so that the pressure of the oil in the circulation pipe and the cleaning pipe is equal to or higher than a certain value. The soaking liquid device is further provided with a control device that inputs a signal from the liquid level gauge to control each of the flow rate adjustment valves so that the liquid level in the slop tank becomes constant.
